Measurements of resistance and capacitance on suspensions of sea urchin eggs were made with an A.C. bridge over a frequency range from 5 to 1000 kd/sec. The data on both unfertilized eggs and fertilized eggs with their developmental changes arrested in acidified sea water were interpreted on the basis of Maxwell's equation, as showing that the cell membrane exhibits a static capacitance, which increases enormously following fertilization. The increase of capacitance occurs in two phases, first abrupt and then gradual.
